My concern with age is... the NFL is a close-knit community and when a guy coordinates for 10+ years, coordinates for one of the most respected franchises, and wins a super bowl... there's often a reason executives aren't knocking on your door.

There's only been one head coach who won a Super Bowl when his first head coaching gig was 50+ years old. Barry Switzer. There's a reason for that. Because when a guy under everyone's radar goes unnoticed for that long, there were probably red flags.
